Tray-type cable bridge is widely used in the oil, chemical, light industry, television, and telecommunications sectors. It boasts light weight, high load capacity, attractive appearance, simple structure, and easy installation. It is suitable for both the installation of power cables and the laying of control cables.
Installation Key Points for Tray Type Cable Bridge
Cable trays and conduits should be laid out in a short and direct path, and they should be installed as close to walls, columns, or beams as possible.
Based on the routing of cable trays and conduits, propose the locations for pre-buried steel plates and loads required for reserved wall holes, floor holes, and suspension installation to the civil engineering and structural engineering departments. Additionally, coordination with the process, plumbing, and power engineering departments should be ensured.

Surface-mounted metal conduit wiring should be closely coordinated with the civil engineering team during design to reasonably determine the wiring paths and equipment selection based on different structural types and architectural layouts.
Cables of different voltages and purposes should not be installed in the same cable bridge.
Cables above 1kV and below 1kV.
(2) Dual-circuit cable supplying primary load from the same path.
(3) Emergency and other lighting cables
(4) Electrical, control, and telecommunication cables. When cables of different grades are laid in the same cable tray, intermediate partitions should be added for isolation.
